D37PX-24

If you want to perform heavy dozing or accurate fine dozing while sitting in a quiet comfortable cab with unrivaled blade visibility, then you need the D37-24 Crawler Dozer. Equipped with an EPA Tier 4 Final certified engine, this dozer has the cab forward design improved blade response, faster work equipment speed, and an additional “fast-blade mode” that improves blade speed for high-speed grading. The D37-24 is extremely maneuverable by providing full power to both tracks during turns or counter rotation steering. It is an ideal choice for any grading or earth moving applications.

Features

Komatsus New Emission Regulations-compliant Engine

New regulations effective in 2014 require the reduction of NOx emissions. In addition to refining the U.S. EPA Tier 4 Interim technologies, Komatsu developed a new Selective Catalytic Reduction (SCR) device in-house.

Komatsu Diesel Oxidation Catalyst (KDOC)

Variable flow turbocharger

Komastu Closed Crankcase Ventilation (KCCV)

SCR with Diesel Exhaust Fluid (DEF)

Auto Idle Shutdown Function

Komatsu auto idle shutdown automatically shuts the engine down after idling for a set period of time to reduce unnecessary fuel consumption and exhaust emissions. The amount of time before the engine is shutdown can be easily programmed from 5 to 60 minutes.

Selectable Working Mode

P mode is the mode designed for powerful operation and maximum production. E mode is designed for general dozing applications, providing adequate speed and power, while saving energy. For fuel reduction and energy savings, the monitor panel allows the operator to easily switch between working modes, depending on working conditions.

P mode (Power mode)

With P mode, the engine outputs its full power, allowing the machine to perform work requiring large production, heavy-load, and uphill work.

E mode (Economy mode)

With E mode, the engine outputs enough power for the work without delivering unnecessary power. This mode enables energy saving operation and is ideal on hard or rough surfaces that often cause shoe slip and work not requiring as much power, such as downhill dozing, leveling and light-load work.

Electronic controlled hydraulic system

Single Pedal (Decelerator/Brake Pedal) to be operated for Speed Control, during Operation

Machine operation is simple because brake function has been integrated into the decelerator pedal. Machine travel speed can be controlled using one pedal. The pedal function can be changed by a mode selector switch.

Decelerator mode: The pedal modulates engine rpms and vehicle travel speed. It can be used for all applications.

Brake mode: The pedal modulates vehicle travel speed while maintaining high-engine speed. This mode can be helpful to maintain work-equipment speed, while using the brake function.

Large Multi-Lingual High Resolution LCD Monitor

A large, user-friendly color monitor provides easy-tounderstand information for the operator. Excellent screen visibility is achieved with a high resolution LCD monitor that is easy to read at various angles and lighting conditions. Simple and easy-to-operate switches and function keys facilitate multi-function operations. The monitor displays data in 26 languages.

Energy Saving Operation

Ecology guidance

In order to support efficient operation, the following four messages are displayed for fuel saving operation. These can be displayed by the operator, if desired.

Avoid Excessive Engine Idling

Use Economy Mode to Save Fuel

Avoid Hydraulic Relief Pressure

Avoid Over Load

Ecology gauge

To help the operator to perform in an environmentally friendly way and minimize energy consumption, an easy-to-read “Ecology gauge” is displayed on the left of the multi-monitor screen.

Fuel consumption display

Average fuel consumption during the day is displayed and updated every 10 seconds.

Additional Operator Convenience Equipment

Rear view monitor system

On the large LCD color monitor, the operator can view, through one camera, areas directly behind the machine. This camera can be synchronized with reverse operation.

Secondary engine shutdown switch

A new secondary switch has been added at the side of the front console to shut down the engine in an emergency.

PAT Dozer with Adjustable Pitch

A power angle power tilt dozer blade with adjustable blade pitch system is available on the D37EX/PX-24. The hydraulic blade tilt and angling function expands versatility and productivity in a variety of applications and manually adjustable blade pitch.

Rear, hydraulically-driven, swing-up fan

The D37EX/PX-24 utilizes a swing-up fan with a gas strut-assisted lift system to provide easy access to the (side-by-side) radiator, oil cooler and charge air cooler. The hydraulic fan has a cleaning mode which enables the fan to rotate in the reverse direction to help clear off objects that are restricting air flow.

Modular design

One of the design goals behind the creation of the D37EX/PX-24 was to manufacture a more durable machine. This was achieved by reducing component complexity and using a strong modular design for increased serviceability and durability. Steel castings reduce the number of welds, improving rigidity and strength.

Parallel Link Undercarriage System (PLUS)

Komatsu's PLUS rotating bush design provides less downtime, longer wear, and with up to 40% lower undercarriage maintenance costs. Rotating bushings eliminate the cost and downtime for bushing turns, and strengthened rollers and links increase wear life up to two times. With PLUS, individual links can be replaced with common track tools.

Easy Maintenance

Planned maintenance and daily checks are the only way to ensure long service life from equipment. That’s why Komatsu designed the D37EX/PX-24 with conveniently located maintenance points to make necessary inspections and maintenance quick and easy.

Robust Guarding And Attachments

Komatsu offers a full guarding package to help protect your machine and operator in severe applications.

Steering System

Palm Command Control System (PCCS) joystick control for all directional movements. Pushing the joystick forward results in forward machine travel, while pulling it back reverses the machine. Simply tilt the joystick to the left or right to make a turn. Tilting the joystick fully to the left or right activates counter-rotation.

Hydrostatic Transmission (HST) provides smooth, powerful turns. Fully electronic control enables smooth control that can be adjusted in the monitor. The PCCS utilizes shift buttons to increase and decrease speed.
